Asaf Jah I,also known as Chin Qilich Khan, was the founder of Asaf Jahi Dynasty. Mughal Emperor Farrukh Siyar gave him the title of “Nizam-ul-Mulk”. His original name was Qamar-ud-din Khan.
The title of Chin Qilich Khan was given to him by Aurangzeb.
As Subedar of the Deccan Nizam-ul-Mulk Asaf Jah, controlled the present State of Andhra Pradesh and portions of Tamil Nadu and Orissa.
In 1727 and 1729, Asaf Jah came into conflict with the Marathas as he refused to accept their claim to levy chauth (a tax consisting of one-fourth of the land revenue).
In 1731, Asaf Jah was defeated by the Marathas and forced to accept their claim.
In 1737 he went to Delhi to assist the emperor. The emperor bestowed the provinces of Malwa and Gujarat on the eldest son of Asaf Jah - Ghaziuddin. But the invasion of Nadir Shah in 1739 convinced Asaf Jah that the Mughal Empire would not last longer. He therefore returned to Hyderabad in 1744 and began to cultivate good relations with the English East India Company at Madras. He died in 1748 at the age of 78. He left behind six sons and a number of grandsons.
